Description
Technical field
Patent of the present invention is related to main axis of gear shaper structure, particularly a kind of with main shaft rotation and the gear shaping toward counter-movement
Owner's axle construction.
Background technology
On existing gear shapping machine and many large scale equipments, commonly using main shaft directly as the powerful main fortune of transmission
Dynamic, its rotary speed is high, fast toward counter-movement, and precision is high.But because the main shaft moment is moving, and main shaft and collar bush
Gap is small, stress is big, lubrication is insufficient, temperature length temperature is fast, cause main shaft easily to pull collar bush and locking main shaft.Particularly
On gear shapping machine, because main shaft has ballistic motion up and down reciprocatingly, main shaft, which damages, make it that the teeth directional of workpiece and profile accuracy are overproof,
Appear directly to damage cutter during main shaft locking.
The content of the invention
The purpose of the present invention is to overcome the shortcomings of above-mentioned technology, there is provided it is a kind of can guarantee that main shaft sufficient lubrication, cooling from
Dynamic lubrication formula main axis of gear shaper structure.
The object of the present invention is achieved like this：A kind of self-lubricate cooled main axis of gear shaper structure, it includes main shaft,
Main shaft is externally provided with collar bush, and main shaft is moved up and down in collar bush and rotary motion, collar bush are set in tool-post structure, in main shaft
The upper end of set is respectively equipped with oil inlet and oil-out, and oil inlet directly connects with helical oil groove, and helical oil groove is provided with collar bush,
The cylindrical of collar bush is furnished with multiple tracks annular cooling bath, and the lower end of annular cooling bath communicates with helical oil groove, main shaft, collar bush, knife
Support body and oil inlet and oil-out form a closing oil path circulatory system.
Coordinate between main shaft and collar bush for gap.
Collar bush is provided with sealing ring.
Only have opening at one to communicate between each annular cooling bath, be open and be symmetrically distributed between adjacent annular cooling bath.
Described helical oil groove is twice.
Self-lubricate cooled main axis of gear shaper structure provided by the invention, twice helical oil groove is machined with collar bush,
Allow whole friction zone oil groove is interior to be full of lubricating oil, the reciprocating motion by main shaft brings oil into friction zone formation lubricating oil film, reaches
Purpose is lubricated, prevents main shaft loss；Cylindrical in collar bush is covered with annular cooling bath, lower end and the oil-way phase of cooling bath
It is logical, only have opening at one to communicate between each annular cooling bath, opening is symmetrically distributed between adjacent cooling bath, and such lubricating oil exists
Each cooling bath is flowed in backhaul, collar bush heat caused by rubbing and impacting is taken away, ensure that the abundant cold of collar bush
But so that collar bush thermal deformation is very small, prevents main shaft fault.
Brief description of the drawings
The invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the structural representation of the main shaft of the present invention.
Fig. 3 is Fig. 2 P direction views.
Embodiment
As Figure 1-3, a kind of self-lubricate cooled main axis of gear shaper structure, it includes main shaft to the structure of the present invention
4, main shaft one end, which is provided with, hangs broach shell 6, and main shaft 4 is externally provided with collar bush 3, and main shaft 4 moves up and down and rotated fortune in collar bush 3
Dynamic, collar bush 3 is set in tool-post structure 2, and oil inlet 1 and oil-out 7 are respectively equipped with the upper end of collar bush 3, is provided with collar bush 3
Helical oil groove 8, the cylindrical of collar bush 3 are furnished with multiple tracks annular cooling bath 9, and the lower end of annular cooling bath 9 communicates with helical oil groove 8,
Main shaft 4, collar bush 3, tool-post structure 2 and oil inlet 1 and oil-out 7 form a closing oil path circulatory system.Main shaft 4 and collar bush
Coordinate between 3 for gap, with gap between 0.005-0.01mm.
The collar bush 3 of the present invention is provided with sealing ring 5, only has opening at one to communicate between each annular cooling bath 9, adjacent
It is open and is symmetrically distributed between annular cooling bath 9, described helical oil groove 8 is twice.
The operation principle of the present invention is as follows：Main shaft 4 can transmit huge impulsive force F when being moved back and forth in collar bush 3
Onto collar bush 3, main shaft 4 also transmits moment of torsion M simultaneously.The gap of main shaft 4 and collar bush 3 is very small, necessarily has on contact surface
Very big impulsive force and frictional force, temperature quick heating, causes main shaft fault.The present apparatus injects certain pressure by oil inlet 1
Lubricating oil, when main shaft 4 moves up and down with rotary motion in collar bush 3, lubricating oil enters by two helical oil grooves 8
To friction zone, allow whole friction zone oil groove is interior to be full of lubricating oil, and rely on the reciprocating motion of main shaft to bring oil into friction zone and formed
Lubricating oil film, reach lubrication purpose, prevent the loss of main shaft 4.
Further, since collar bush 3 is cylindrical to be covered with annular cooling bath 9, the lower end of cooling bath 9 communicates with oil-way 8, due to
Only have opening at one to communicate between each annular cooling bath 9, be open and be symmetrically distributed between adjacent cooling bath 9, such lubricating oil exists
Each cooling bath 9 is flowed in backhaul, the heat caused by rubbing and impacting of collar bush 3 is taken away, ensure that the abundant of collar bush 3
Cooling so that the thermal deformation of collar bush 3 is very small, prevents the fault of main shaft 4.
